GAS-DISTRIBUTION SYSTEM.

' Application filed June 11.

To all whom it may concern.-

Be it known that I, GID ON HAWLEY DI- ALL, a citizen'of the UnitedStates, residing at Terre Haute, in the county of Vigo and State ofIndiana, have invented certain new and useful Improvements in GasDistribution; and I do hereby declare the following to be a full, clear,and exact description of the invention,- such as will enable othersskilled in the art to which it use the same.

This invention relates to systems for supplying illuminating-gas tosmall towns; and it consists in the novel system and combination ofparts hereinafter fully described and claimed whereby a series of smalltowns are supplied from a single gas-producing plant located at adistance from them.

The drawings show a ratus used for carrying of this invention.

The illuminating-gas is manufactured economically and upon a large scaleat any convenient central point, which may be a large city, and it isdistributed to a series of small towns surrounding the said centralpoint by means of tank-cars. These tank-cars are preferably run uponrailroads to the various small towns, and the gas from the tanks istransferred to the gas-mains of the small towns after being suitablyenriched with hydrocarbons.

A is a portable gas-tank mounted on a car B, which runs upon rails I).These rails extend between the central point where the gas is producedand the small town or towns where the gas is to be used.

0 is a stationary tank for holding compressed gas at the small townwhere the gas is to be used, and c are portions of the gas mains of thesaid small town.

D is an outlet-valve connected to the tank 0, and d is apressure-regulator of any approved construction connected to the saidappertains to make and out a preferred form valve.

E is a. saturator for holding hydrocarbon. This saturator is arrangedbetween the pressure-regulator and the gas-mains c and is of anyapproved construction.

gas-compressor F is mounted upon the car and is connected to thegas-tank by a pipe f, provided with a stop valve. G is a saturator alsocarried by the car and connected to the said gas-compressor by a pipe 9,also provided with a stop-valve.

Specification of Letters Patent.

diagram of the appa- Patented Feb. 26,1907. 1906. Serial No. 321,137-

H is a pipe provided with a stop-valve h and connecting the saturator Gwith the stationary gas-tank O. This pipe H is provided with suitablecouplings, so that it may readilybe connected to and disconnected fromthe saturator or the tank.

The gas is manufactured in any suitable gas-producing apparatus and iscompressed into the portable tank A to a pressure of from ten to twentyatmospheres by means of any suitable gas-compressor. (Not shown in thedrawings.) In thus compressing the gas the moisture and some of thehydrocarbons are pressed out of it, and thus the compressed gas isrendered too dry. The substances thus compressed out of the gas arecollected and are placed in the saturator G upon some absorbentmaterial, such as coke or cotton.

When the portable tank arrives at the small town where the gas is to beused, it is transferred under pressure to the stationary gas-tank. Thegas compressor or pump F forces the gas through the saturator G into thestationary gas-tank C. In this manner the gas is enriched with thehydrocarbons previously extracted from it and is stored under pressure,so that the portable gas-tank can be taken away.

When the gas is admitted to the gas-mains at the normal pressure atwhich it is to be used, it is conducted through the saturator C, whichalso contains suitable hydrocarbons, such as benzol or gasolene, bymeans of which it is raised to the preferred candle power andrendered'suitable for consumption.

This system of gas distribution can be modified in various ways. Theportable tank-car can be connected direct with the gas-mains of thesmall town by means of the necessary piping, valves, gas-regulator, andsaturator. When this is done, the car has to I remain at the small townuntil empty.

The portable gas-tank can be connected to the stationary gas-tank bymeans of suitable piping, and the two tanks thereby connected, withoutusing a compressor, until the, pressure of gas in both becomesequalized, or a gas-compressor at the stationary tank can be used toiillthe stationary tank at high pressure instead of a gas-compressor carriedby the car. The tank-car on its arrival at a small town can also beconnected to a gasholder of ap roved construction as ordinal rily used,an the gas from the portable gastank can be allowed to flow into thesaid gasholder so that it may be supplied to the main for use in theordinary manner.

On its first arrival at a small town the portable gas-tank can first beconnected to a stationary storage-tank until the pressure in the twotanks is equal. The portable gas-tank can then be disconnected from thestationary gas-tank, and the remainder of its contents can be allowed toflow into anordinary gasholder at low pressure and subsequently used inthe gas-mains in the ordinary way.

What I claim is- 1. In a system for distributing gas, the combination,with a portable tank for transmitting gas under pressure, of astationary gas-tank provided With means for connecting it with thegas-mains, a detachable connection between the said tanks, and asaturator arranged between the said tanks and operat ing to enrich thegas in its passage from the portable tank to the stationary tank.

2. In a system for distributing gas, the

combination, with a portable tank for holding gas under pressure, of astationary gastank connected with the mains, a detachable connectionbetween the two said tanks; a saturator arranged in the said connectionbetween the two said tanks, and a second saturator arranged between thesaid stationary gas-tank and the mains.

3. In a system for distributing gas, the combination, with a portabletank for holding gas under pressure, and a car carrying the said tank,of a gas-compressor and asaturator also carried by the said car andconnected with the said tank, a stationary gas-tank connected with themains, and a detachable connection between the said saturator and thesaid stationary gas-tank.

In testimony whereof I have aflixed my signature in the presence of twowitnesses.
